.TULIUS TUTEUR, OF CLEVELAND, CHIO.

ICIST-HANGER.

Specification of Letters Patent.

Patented July 2, 1907.

Application filed May 13,1907. Serial No. 373,259.

To all whom it may concern:

Be it known that I, .'IULIUs TUTEUR, a citizen of the United States ofAmerica, and a resident of Cleveland, in the countyof Cuyahoga and Stateof Ohio, have invented certain new and useful Improvements in Joist-Hangers, of which the following is a specification.

My invention relates to improvements in stamped metal hangers forjoists, and has for its object the provision of a hanger integrallyformed, as far as possible, from'sheet metal of sufficiently heavy gageand provided with a simple reinforcing member or members affordingmaximum strength for the weight of metal used.

More particularly, my invention further contemplates the provision of awide bearing surface for the hanger without increase in expense or theloss of metal, whereby the supported weight is distributed over agreater area of the wall wherein the hanger is embedded.

Experience has shown that a broad supporting-piece is desirable fordevices of this type,A since instances of the collapse of buildings havebeen directly traceable to the fracture or crushing of the supportingwall by a heavily loaded hanger equipped with an inadequate supporting-member.

The preferred wall hanger of my invention, as will be at once observedfrom the accompanying drawings, preferably is bl anked out from anintegral sheet of mild steel, and is provided with two re-enforcingpieces or p members of angle iron. These are not absolutely essentialbut contribute in a marked degree to the strength p A dering it veryeasy to shape and secure together.

From the drawings, it is seen that the preferred wall hanger consists ofan integral primary or body member suitably folded to provide a broadsupporting seat and a ledge for the timber or joist carried from alowerplane, while a re-enforcing back-piece, Figure III, may be stamped out,shaped and riveted thereto to stay the same, and a cross-piece, Fig. IV,may be similarly secured to the joist receiving seat of the hanger.

The following specification will make further particular reference tosaid drawings, wherein Fig. I is an enlarged perspective view of thepreferred type of my improved hanger. Fig. II is a plan view of theblank from which the hanger is formed. Fig. III is a similar view of theblank for the re-enforcing piece uniting the side arms. Fig. IV showsthe angle-iron re-enforcement for the joist seat; and Fig. V is a planview upon a much smaller scale of a modified type of hanger, whil'e Fig.VI is a fragment of its blank.

Throughout the several figures of the drawing, I have employed the samecharacter of reference to indicate similar parts.

Fig. II well illustrates the primary member a as formed from a singleplate or sheet of metal, such as wrought iron or steel. This member isprovided with lateral wings a. which are adapted to be folded at rightangles upon the lines l, I forming the side pieces for the hanger. Parto12 thus forms the joist seat, which may be re-enforced, if required, bythe rigid crosspiece b of angleiron'suitably riveted or secured. inplace. The back of the hanger is formed from the rear portion a3 foldedat right angles Aupon line 2, and the broad 'supportingdedge a4 is againfolded back at right angles with part a3 along line 3. 'lhe lines 4, 4indicate the position of the side pieces, and accordingly lateral wingsa5 a5 integral with the back and supporting-ledge serve to distributethe weight of the joist over a relatively large area. These wings may beof any suitable width, but ordinarily they are proportioned as i hereinshown, and avoid loss of any substantial amount of metal in constructingthe hanger. As shown in Fig. V, these wings a a6 may be integral withthe side pieces a, and with a slight increase of expense, serve furtherto stay the hanger and distribute the weight. Both of these formspreferably are provided with a re-enforcing member c formed ofangle-iron angularly notched at c/ c, and folded or bent at right anglesfrom the apexes of the" angle c to form a box-like re-enforcing part;the blank therefor being shown in Fig. III. The forward portion thereofforms a back for the joist hanger, while the angular faces of the outerends are respectively riveted to the side pieces a/, and thesupporting-ledge a, thereby tying the side pieces together and rigidlystaying the entire Structure.

The above-described type of structure has been given rigid tests, and ithas been found that the integral structure not only affords economicaland thoroughly practical support for joists or timbers, but that themetal thereof is most advantageously disposed to withstand thesupporting strain to which an article of this type is subjected. Thisstrain in turn is carried by a relatively broad supporting-ledge or seatbearing over a large area of the wall, and thereby avoiding the crushingaction observable in other types of hanger. Particularly is this ofadvantage where the hanger is embedded in walls of comparatively softbrick or stone, and this deficiency in the building material iscompensated for 'by the peculiar yconstruction herein set forth. i

The side pieces, it is seen, form an integral part of the joist seat andextend straight back to bear upon the wide supporting-ledge, whereon itis re-enforced by member c. The angle-iron cross-piece b not only servesto stiffen or stay the joist seat'a2, but serves as well to retain thetimber, which preferably is cut out to accommodate this part. Asindicated, however, such re-enforcement s not essential and may beomitted, particularly in hangers ol lighter construction.

From the foregoing, it Will be appreciated that a hanger of approvedtype may be constructed in accordance with my invention from either one,two or three parts, suitably shaped and riveted together, as I haveherein explained.

Having noW set forth the preferred embodiment of my invention, I claimas new and desire to secure by Letters Patent, the folloWing:-
